Create PHP classes / functions to emulate a poster on classified sites

Create PHP classes / functions to emulate a poster on classified sites. Classes are needed for: 1. [login to view URL] 2. [login to view URL] 3. [login to view URL] 4. [login to view URL] (mobile version of the site) Each class must contain functions that a poster may need, specifically: * Login * Post ads, including category, title, description, photos, etc. * View own ads * Edit own ads * Delete ads * Create account * Delete account (if supported) * Logout Data (account usernames / passwords, ad content, etc.) is stored in MySQL DB. Ad photos are stored in filesystem. User interface is not needed. Diagnostic text output only. Must be written using PHP and cURL, using best practices and as many built-in cURL functions as possible, custom headers only if necessary. Should emulate a standard user / browser as much as possible, so it's hard to tell it's a script, not an actual user. No web scraping or spamming is involved, this is strictly a time saving solution.
